Question

based upon this double bar graph what can you infer about the amount of kinetic energy that the moving cart has in each type of collision? average forces during car collisions collision a collision b car type the amount of kinetic energy decreases from collision a to collision b the amount of kinetic energy increases from collision a to collision b the amount of kinetic energy remains the same from collision a to collision b the amount of kinetic energy has changes between colliding carts but remains the same from collision a to b

Explanation:

Step1: Recall kinetic - energy and force relationship

Greater force in a collision generally implies greater kinetic - energy (assuming similar conditions like mass and time of collision).

Step2: Analyze the bar - graph

The average force for collision B is greater than that for collision A for the moving cart (as seen from the height of the blue bars).

Step3: Infer about kinetic energy

Since greater force in a collision (for the same object) usually means greater kinetic energy, the amount of kinetic energy increases from collision A to collision B.

Answer:

The amount of kinetic energy increases from collision A to collision B
